Interface RootPaneContainer

All Known Implementing Classes:

JApplet, JDialog, JFrame, JInternalFrame, JWindow

public interface RootPaneContainer

Unsafe: This interface is implemented by components that have a single JRootPane child: JDialog, JFrame, JWindow, JApplet, JInternalFrame. The methods in this interface are just covers for the JRootPane properties, e.g. getContentPane() is generally implemented like this:

     public Container getContentPane() {
         return getRootPane().getContentPane();
     }
 

This interface serves as a marker for Swing GUI builders that need to treat components like JFrame, that contain a single JRootPane, specially. For example in a GUI builder, dropping a component on a RootPaneContainer would be interpreted as frame.getContentPane().add(child).

Method Summary

Container	getContentPane() Enabled: Returns the contentPane.
Component	getGlassPane() Suppressed: Returns the glassPane.
JLayeredPane	getLayeredPane() Suppressed: Returns the layeredPane.
JRootPane	getRootPane() Suppressed: Return this component's single JRootPane child.
void	setContentPane(Container contentPane) Suppressed: The "contentPane" is the primary container for application specific components.
void	setGlassPane(Component glassPane) Suppressed: The glassPane is always the first child of the rootPane and the rootPanes layout manager ensures that it's always as big as the rootPane.
void	setLayeredPane(JLayeredPane layeredPane) Suppressed: A Container that manages the contentPane and in some cases a menu bar.

Method Detail

getRootPane

public JRootPane getRootPane()

Suppressed: Return this component's single JRootPane child. A conventional implementation of this interface will have all of the other methods indirect through this one. The rootPane has two children: the glassPane and the layeredPane.

Returns:

this components single JRootPane child.

setContentPane

public void setContentPane(Container contentPane)

Suppressed: The "contentPane" is the primary container for application specific components. Applications should add children to the contentPane, set its layout manager, and so on.

The contentPane my not be null.

Generally implemented with getRootPane().setContentPane(contentPane);

Parameters:

contentPane - the Container to use for the contents of this JRootPane

See Also:

JRootPane.getContentPane(), getContentPane()

getContentPane

public Container getContentPane()

Enabled: Returns the contentPane.

Returns:

the value of the contentPane property.

See Also:

setContentPane(java.awt.Container)

setLayeredPane

public void setLayeredPane(JLayeredPane layeredPane)

Suppressed: A Container that manages the contentPane and in some cases a menu bar. The layeredPane can be used by descendants that want to add a child to the RootPaneContainer that isn't layout managed. For example an internal dialog or a drag and drop effect component.

The layeredPane may not be null.

Generally implemented with

 
    getRootPane().setLayeredPane(layeredPane);

See Also:

getLayeredPane(), JRootPane.getLayeredPane()

getLayeredPane

public JLayeredPane getLayeredPane()

Suppressed: Returns the layeredPane.

Returns:

the value of the layeredPane property.

See Also:

setLayeredPane(javax.swing.JLayeredPane)

setGlassPane

public void setGlassPane(Component glassPane)

Suppressed: The glassPane is always the first child of the rootPane and the rootPanes layout manager ensures that it's always as big as the rootPane. By default it's transparent and not visible. It can be used to temporarily grab all keyboard and mouse input by adding listeners and then making it visible. by default it's not visible.

The glassPane may not be null.

Generally implemented with getRootPane().setGlassPane(glassPane);

See Also:

getGlassPane(), JRootPane.setGlassPane(java.awt.Component)

getGlassPane

public Component getGlassPane()

Suppressed: Returns the glassPane.

Returns:

the value of the glassPane property.
